At a news conference on September 22, President Trump claimed that taking acetaminophen, the active ingredient in Tylenol, during pregnancy “can be associated with a very increased risk of autism.” Many experts have pushed back on the statement, saying it’s a false claim that downplays the risks of fever during pregnancy, which Tylenol may be used to treat.Autistic people and their families also raised concerns about the language used and the premise that autism is a scourge that needs to be eliminated.Host Flora Lichtman digs into what we know about acetaminophen use during pregnancy with epidemiologist Brian Lee, who led one of the largest peer-reviewed studies looking at the link between acetaminophen use during pregnancy and autism in children.Guest: Dr. Brian Lee is a professor of epidemiology at Drexel University, based in Philadelphia, Pennsylvania.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
